Iptables - Group Of Hosts

Is there any way in Iptables of being able to include a group of hosts to be able to access a service.

For example I have 3 machines on my network that I want to accept ssh connections to my machine but no others

Rather than doing this:

iptables -A FORWARD -s -d -p tcp --dport ssh -j ACCEPT

iptables -A FORWARD -s -d -p tcp --dport ssh -j ACCEPT

iptables -A FORWARD -s -d -p tcp --dport ssh -j ACCEPT

You could figure out how masks work and try it that way ( although at most you'll be stuck with 4 hosts in the range, not the 3 you want ), or you could also do your /etc/hosts.allow and /etc/hosts.deny
